For me personally, the winner is the port of Ubuntu Touch from Joel for the Xiaomi Poco F1 :

thanks, Joel, for your great work.
@josele13 Thanks for your detailed answer. Your profound advices are very helpful. I have to study this in detail.
@c0n57an71n I admit, this is an advantage of the PinePhone. I also miss a dual boot option for Ubuntu Touch. Some apps only work on newer Android releases. I currently carry around three different Samsung Galaxy S5 devices with different Android versions. Each for it's on purpose. One for ANT+, one for writing capability to the SD card, and one for phone calls the latest Android apps. With Ubuntu Touch, there will be one device more. Multi boot could solve the problem.
@flohack I don't agree with flohack. Even when developers are not present in the forum, every knowledge about devices is precious. For instance, there is a problem with the different types of Xiaomi devices, which their exact model naming. A subfolder for each Xiaomi device which is ported, or generally for each device which is ported would be helpful. Every port is precous work and deserves a subfolder, a subfolder for each device someone requests. Even if there is no further developement for a device, it is good to know the different devices, their naming, and what is working, and what is not working. This can help which device to choose. Else this information is scattered everywhere.
I don t have this device either, and I am not a porter as well, but I appreciate your work very much. Every contribution to the Ubuntu Touch community is helpful.
@tchan the developement of the Xiaomi Redmi 7 seems to make progress. Could you inform us, when the Ubports installer for the Redmi 7 is there?
I hope this phone will be in the official list soon.
@ tchan Yes, if the Ubports Community wants to be a contemporary and up to date Community, they will put the Xiaomi Redmi 7 on the list of the official supported devices, as soon as the installer is there.
@tchan Thanks tchan. Thanks for not deleting this post.

I am looking for a programmer who has fun to port the Adafruit Open Source Bike Computer to a Ubports device :

The Adafruit software is great, but the platform Adafruit Clue on which the sports computer runs is very limited.
An advantage of the Poco F1: I suppose it should be possible to use it with an usb-c adapter, for instance to get an additional port for charging, HDMI, keyboard and other periferals:
Xiaomi Redmi 7 Onclite has no usb-c, only micro usb.
@tchan oh, I unterstand. For maturity data, ask Tchan.
@tchan Thanks, Tchan. Which model it is can be seen under settings and device on your Xiaomi device. I explicitly asked the UK seller about the model, one has to be careful. Xiaomi Redmi Note 7 would have an installer, which makes things easier. But I think it is worth doing the work for the Onclite installation. There is much info available from Tchan, thank you again. I don t know how it is for the Xiaomi Redmi Note 7. It is lower down the Ubports maturity scale. But what does this say?
@ velkala
I did not yet flash a Ubuntu Touch phone, but several Android custom ROMs. The fist one was really hard work, but then it became easier. There are some instructions on youtube for Xiaomi Redmi XX. To flash a Redmi 7 should be similar to flashing those:
Thank you Tchan for your answer, really convincing. Tchans Ubuntu Touch channel in the Ubports forum is really great, and I love it.
I bought my first Xiaomi Redmi 7 in UK on ebay. First, it was returned due to lacking invoice, then the seller sent it by UPS to the wrong adress in UK, third attempt, she sent it with incomplete invoice. So I sent the invoice from ebay to the custom service. The device arrived. Unfortunately, it was a Redmi Note 7, and not a Redmi 7, so I will return it. Five weeks are gone now since I bought it.
The PinePhone I sold on ebay also arrived in Bergamo, Northern Italy after 5 weeks, due to Corona, and Italian mentality. Swiss post told me that it would be there in 7 days maximum.
Now, I bought a Xiaomi Redmi 7 on Ricardo Switzerland for 50 USD. A second one I missed, since someone was faster than me, but I will go in bidding.
User reported problems that Xiaomi Poco F1 Ubuntu Touch often reboots. What about Xiaomi Redmi 7?
